Two-dimensional array: A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array. This is useful for storing same type of multiple sets of data in same place. The main advantage is that one-dimensional array can hold only one set of value whereas two-dimensional array can hold multiple sets of data in the form of rows and columns. The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns. The number of elements of an array can be calculated by multiplying the number of rows and number of columns of the array. Example: //Declaring multi-dimensional array double testmarks[5][5]; The above statement is used to create a multidimensional array with “5” rows and “5” columns; the first subscript (that is square bracket) is used to refer the number of rows and the second subscript is used to refer the number of columns. The data type “double” represents that the array will hold only “double” type of data. The “testmarks” array can hold 25 elements (that is 5 × 5 = 25 ).

Program Plan Intro

Two-dimensional array:

A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array.

This is useful for storing same type of multiple sets of data in same place.

The main advantage is that one-dimensional array can hold only one set of value whereas two-dimensional array can hold multiple sets of data in the form of rows and columns.

The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns.

The number of elements of an array can be calculated by multiplying the number of rows and number of columns of the array.

Example:

//Declaring multi-dimensional array

double testmarks[5][5];

The above statement is used to create a multidimensional array with “5” rows and “5” columns; the first subscript (that is square bracket) is used to refer the number of rows and the second subscript is used to refer the number of columns.

The data type “double” represents that the array will hold only “double” type of data.

The “testmarks” array can hold 25 elements (that is 5 × 5 = 25 ).

Make the following game user friendly with GUI, with some simple graphics The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.
